Title: Heating-resistor type air flow-rate measuring device and correcting device for internal combustion engine
Inventor: KAWASAKI TSUTOMU
IPC: F02D35/00
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To make it possible to measure the flow rate of air highly accurately even under the pulsation flow state by measuring the counterflow time by utilizing the rising and trailing of an output waveform, and correcting the error from the time. SOLUTION: When heating resistors 1a and 1b are arranged in a main air path and a secondary air path 4, respectively, the resistors sensitively react with a downflow 2. For a counterflow 3, the sensitive reaction occurs in the main air path. Since the counterflow does not enter into the secondary air path 4, there is no detection for the counterflow. Therefore, each output waveform indicates the approximately same waveform at the time of downflow and indicates the different waveform at the time of counterflow. Especially the rising and tailing of the waveform are equal at the time of downflow. On the contrary, the rising and trailing indicate the opposite directions at the time of counterflow. Therefore, when the rising and trailing are always monitored, the flow direction signal can be taken out.  When the rising an trailing are detected are found to be equal, it is judged that there is no counterflow, and the correcting value is made to be zero. When they are different, it is judged that there is the counterflow, and the time of counterflow is measured. The correcting value for the counterflow component is operated by the time, and the correction is performed.

Abstract: PURPOSE:To prevent the body of an operator from being caught in between a paper receiving table and a floor face by providing a control part for stopping the moving action of a supporting mechanism based on the detected output of a detector, in the captioned device for a line printer device, etc. CONSTITUTION:When a paper receiving table 10 is drawn out of a supporting mechanism 11 in order to take out a continuous sheet of paper 8 from the top of the paper receiving table 10, a detector 14 detects this and inputs a detected output indicating that the paper receiving table 10 is drawn out into a control part 13.

Also, even when the control part 13 has already issued a moving direction to move the supporting mechanism 11 upward or downward to the reciprocating mechanism 12, if a detected output from the detector 14 is inputted in it, the control part 13 immediately cancels the moving direction to the reciprocating mechanism 12, and holds the supporting mechanism in the stopped condition.
